parallel transformer question
Hi Timmie- thanks for the book shipment. I'm reading your hydronic controls book (i bought them for my apprentice and found myself reading them instead) and have a question about paralleling transformers. I want to make sure i have this right. You have a very good description of HOW to do this but i want to make sure i have it right in my head as to Why i may want to do this.
Am i correct that for example, a no heat call at midnight, and its a blown 75 va transformer on a weil mclain LGB, am i correct that i could take two 40 va transformers and wire them in parallel if i didn't have the 75 va on the truck?
Also am i correct that it is desirable to have twice the va rating as is required?
Thats what i was getting out of reading your manuals anyways, and i hadn't heard that before so i wanted to clarify.
Thanks again for making those manuals available for purchase for those of us who cant make the trip to your school.
